Just now I've noticed that one of the common excuses for Fallout 4's dialogue wheel, that it "surprises players themselves", is also used for games like Mass Effect and the latest Dragon Age. So, I'm curious. Why do people enjoy being "surprised" by their own character's lines when playing RPGs? (Of course, this doesn't apply to everyone). Now, I perfectly understand why this would be the case in interactive fiction like Telltale games (Walking Dead) and David Cage/Quantic Dream (Heavy Rain) games, or even in exceptions to RPGs like Alpha Protocol or the Witcher (yes, I know this part is a reference, but still), where the character is somewhat established well and is a character you're directing through a path rather than controlling directly. I get that people would enjoy the "movie aspect" of being surprised by the words and actions of their directions (as seen in the linked example above). But RPGs where you create your own character? Really? If you're directly roleplaying a character, why would one not want to fine-tune their words? Especially when RPGs are one of those genres where your words matter. I mean, in RPG games, saying the wrong thing can end very badly. It's just curiosity, really - is there anyone who can explain why anyone would want to not know exactly what your character is going to say?
